Biologists have their fruit flies and rats, psychologists have students. An overwhelming amount of behavioral science is conducted with young people at universities on the assumption that it’s safe to generalise from this species of human to people more generally. There are some common-sense reasons for thinking this might be a problem and also some more specific issues, which we’ve documented before, such as that burnt out students could be skewing the findings.

Now a recent study in PLOS One shows that the ways students differ from the public is different depending on which country you’re in, meaning it’s extra complicated to figure out if and when it’s appropriate to extrapolate student-based findings to people as a whole.

In this era of “fake news” and rising populism, encountering conspiracy theories is becoming a daily phenomenon. Some people usually shrug them off – they find them too simplistic, biased or far-fetched – but others are taken in. And if a person believes one kind of conspiracy theory, they usually believe others.

Psychologists are very interested in why some people are more inclined to believe in conspiracy theories, especially since the consequences can be harmful: for example, by avoiding getting their kids vaccinated, believers in vaccination conspiracies can harm wider public health; in other cases, a belief in a conspiracy against one’s own ethnic or religious group can foment radicalism.

One of the main differences between conspiracy believers and nonbelievers that’s cropped up in multiple studies is that nonbelievers tend to be more highly educated. For a new study in Applied Cognitive Psychology, Jan-Willem Van Prooijen at VU Amsterdam has conducted two large surveys to try to dig into just what it is about being more educated that seems to inoculate against belief in conspiracy.
